    x = - 119/3 = - 39 2/3

    Step-by-step explanation:

    (128 + 7x - 12) = (4x - 3)

    Combine like terms

    (116 + 7x) = (4x - 3)

    Subtract 4x from each side

    116 + 7x-4x=4x-4x-3

    116 + 3x = - 3

    Subtract 116 from each side

    116-116 + 3x = - 3-116

    3x = - 119

    Divide each side by 3

    3x/3 = - 119/3

    x = - 119/3

    x = - 39 2/3
